Today I demonstrate my new 16 ton Chinese hydraulic wire crimper that I bought from Amazon. I will be using it with 4/0 (four aught) 100% copper, fine stranded welding cable and per-tinned crimp lugs. I even cut apart the finished crimped fitting to inspect the quality of the crimp connection. I bought this crimper to use on a starting unit for heavy equipment that we were building a few months ago and I was impressed with it’s capability, especially for the low cost of the tool. I figured it was worth sharing my experience with the good people of Garage Topic and youtube. Harbor Freight offers a hydraulic crimping tool also, but it costs more than the tool in this review, and it’s a smaller crimper. The largest wire listed on the Harbor Freight tool is 0 AWG (zero gauge). The cable I am crimping in this review is 4/0 (four aught) which is four sizes larger than 0 AWG. (zero gauge) This 16 ton Chinese crimper comes with 5 sets of dies LARGER than the 4/0 I was crimping. (11 sets of dies in total) This thing is an absolute beast for the price. I should have bought this tool sooner!

I am pretty sure that most of the 16 ton hydraulic crimpers listed on Amazon and eBay are probably from the same factory in China. They are just re-named, or re-branded depending what the private sellers decide to call the product in their Amazon or eBay listings. The unit I purchased from Amazon is called “Goplus”.

This is a picture of the hydraulic crimping tool I purchased:

PROS:

• Low cost. I do not remember the exact price that I paid for this crimper but it was considerably cheaper than the Harbor Freight crimper, which is also considerably smaller than this unit. Not to mention, this crimper is WAAAY cheaper than the well known, brand name crimpers that is available on the market.

• Capability. This crimper comes with eleven hex dies which will cover a wide range of cable and wire sizes. Everything from a wire just large enough that you wouldn’t want to crimp it with a hand crimper, all the way up to cable sizes that your average guy would probably never be working with anyway. Another thought I had was…. the dies are nothing proprietary. They literally look like a square piece of metal with a hex hole punched in the middle, then cut in half to make the die. A handy guy in his home shop could easily make custom dies for this crimper out of a square piece of mild steel, drill a hole, then cut in half. Presto! Instant custom die.

• Simple and easy to use. This crimper is very easy to use. There is one vale to open and close just like on a hydraulic floor jack, and a handle to pump the hydraulic jaws together. That’s it. (The jaws are spring return) As long as you have the correct size dies installed for the size of cable and fittings you’re using, and you center your fitting in the dies, you really can’t screw up the crimp. Then you just pump the handle until the dies come completely together, so there is no longer a gap between the dies. Done.

• Complete kit. The crimper comes in a blow mold case, which is not very good quality, but the only thing the case does is hold the tool and dies together while being stored. The case does not affect the functionality of the tool while it’s crimping wire or cables. And besides, for the cost of this tool, I really didn’t expect the case to be great anyway. lol. It also comes with an extra set of o-rings so when the tool develops a leak in the future, you will already have the o-rings to fix the leak….. if the extra o-ring kit isn’t lost by then. lol

• Quality of crimp. I was very impressed by the quality of the finished crimp. Between the size of dies I was using, and the size of the fittings and cable I was crimping, I was VERY happy with the result of the finished crimp. I used my sawzall to cut a test crimp apart to inspect the crimp quality and it looked perfect to me. See for yourself below:

CONS:

• My number one complaint is die sizing. The numbers on the dies are not inline with any numbers used for wire sizing here in North America, not this part anyway. I’ve been told it’s some sort of metric wire sizing….. which is perfectly fine, but it’s just not very convenient of anyone in North America. You would think if they’re selling millions of these crimper kits here in North America, it wouldn’t be too much trouble to have a different set of dies stamped with AWG sizing. It takes a little trial and error to get the correct size die for your project. I recommend at least one or two test crimps with scrap wire to make sure you get the sizing correct before crimping anything on your project itself. I was mildly upset with the die sizing but then I remembered how much I paid for this crimper kit and I immediately had a smile back on my face. lol.

• Other than die sizing, and the low quality case, there really is nothing else to complain about with this hydraulic crimping tool.

Conclusion:

I would absolutely recommend this hydraulic crimper to anyone who needs to crimp any wire or cable that is too large to crimp with a hand crimper. It is a complete kit that covers a wide range of wire and cable sizes, it is very easy to use, it gives very high quality crimp results, and is very reasonably priced. The only down side would be if you’re a commercial contractor, who needs to prove that he used certified crimp fittings with a certified crimper, on a commercial job, then this crimper would not be for you. However, if you found yourself in the situation that I just mentioned, you’re probably not reading this review anyway. You would most likely be standing at the city desk of your local electrical supply house picking up that well known, brand name crimper that I mentioned earlier in this post, and paying 60 times (roughly) more than I paid for the crimper in this review.

For the average guy who is looking to crimp heavy gauge welding cable, or battery cables, or even cables for your DIY solar system install, this crimper would be excellent for you.
